Problem Statement:
AtCoder Beginner Contest usually starts at 21:00 JST and lasts for $100$ minutes.
You are given an integer $K$ between $0$ and $100$ (inclusive). Print the time $K$ minutes after 21:00 in the `HH:MM` format, where `HH` denotes the hour on the $24$-hour clock and `MM` denotes the minute. If the hour or the minute has just one digit, append a $0$ to the beginning to represent it as a $2$-digit integer.
